Are you sure your judgment isn't being altered by having the example of Steve Jobs in mind? If someone tricks you out of a substantial sum of money, it's a bit of a stretch to presume it's likely they have world-changing taste. Typically, people willing to trick their friends are not people you want to be friends with, and Jobs is the exception rather than the rule. His ability to make money off you does not mean you'll get a reasonable share of that money.
